Hiya, I had a moderate to large one at 6 weeks and was put on bedrest for a week. A few days after the initial bleed, I had another episode of bright red bleeding which freaked me out all over again. When I had a scan the day after the first bout, we were told that my body would either reabsorb the blood, it would slowly bleed and resolve that way or worst case scenario, because it was quite big, I would miscarry. After the second lot of bleeding, I would have a few days of nothing, then start bleeding old blood for a few days, stop for a few then start again. We were told by our fertility clinic that as long as it was brown blood, then that was ok, though it is pretty disconcerting when every time you think the bleeding has stopped, it starts up again. I was having scans weekly, bleeding on and off the whole way with little change in haemorrhage appearance on the scan but am pleased to say that at my last scan (about a week ago), there was no more evidence of blood - YAY!!!!! Though in saying that, when I had a scan at 8 weeks, the sonographer remarked that she wouldn't be surprised if it was still there in two months so they can hang around and everything still be ok.

It is damn scary and even now, I am taking things really easy i.e. no heavy lifting, resting when I feel tired, I have only just started going for short, gentle walks again (I was running approx 30 - 40km a week before I started stims for the ivf cycle that got me pg) so basically being a bit of a couch potato as much as possible. Don't freak out heaps if you do get episodes of brown spotting - as I said, I had it for a good 3 - 4 weeks and from everything I have read about subchorionic bleeds, this is perfectly normal.

Good luck for the rest of your pregnancy, hope things resolve quickly to give you peace of mind and hopefully let you relax and enjoy your pregnancy
